Find both roots of each equation and state the relation. I. $x^{2} - 21 x + 110 = 0$
II. $y^{2} - 19 y + 90 = 0$

Competition practiceQuadratic Comparison

A $x$ ≤ $y$
B $x$ ≥ $y$
C $x > y$
D $x < y$

Step-by-Step Solution

x = 10

or 11;

y = 9

or 10.

x

is never below

y

and

x = y = 10

is possible, so

x

≥

y

.

Answer: B)

x

≥

y
